dirty maf sensor from K&N. so for those who purchased the new KN intake or have the K&N in any form, make sure you get a MAF cleaner because it will soon catch up with you in the long run; like me. so I'm not telling everyone to ditched their K&N from my experience, just do regular maintenance.

 

The K&N can oil the sensor, but it wont cause the car to go into LIMP mode.

@1badBlueBerrySC you've never gotten one of those SUUUUUPER oiled filters out of the box. Kind of looks like a 5 Guys Burger? Lol. I agree the dealer bullshit you though. I fixed the issue just by relocating where the line ran with a single zip tie and I no longer have the issue. It is fixed for a dollar..

 

well I have the stock airbox on already after it happend and with the Hahn intake before. the reason my car went into LIMP mode before is that my Hahn Intake and Injen CP had little leaks to cause it to go into LIMP mode. If its my Injen CP, then I'll tell them what they can do with themselves. I can't remember which forum it was, but a guy took a toothpick and showed where his leak was when he first got his Injen CP.

 

Do you have T Bolt clamps on it?

 

Well, like I said, I cleaned my maf and I'm still having the same issue.

 

yes, after I had the Injen CP leak for the first time when I messed with it because I had a ghetto idea and maybe not put it back on right. that's when I purchased some t-bolt clamps from siliconintakes.com

 

You need to try moving your lower sensor wires like i did

 

UPDATE: My car is running normal with the stock filter and I cleaned the MAF sensor with the CRC Mass Air Flow cleaner did two runs with no issues.

 

Well Idk if I found the issue or not but I don't think they have the right calibration code in my car. The code that's in my car now is 12629314 and according to the gms1 instructions the code is suppose to be 12633785? Can anyone tell what calibration is actually on the car by the vin number?

 

some1 has to show me how to make a leak tester cuz im curious if my pipes are leaking. runs fine but im misfiring here n there n throwing weird fuel trims n i think a leak might be it.

Also, some1 take a pic of the LNF stock wideband. IDK where to find it at. I know its on the turbo manifold somewhere but a pic would help.

 

I agree!

Day 11 for me with the K&N filter out, STILL no problems.

As for all of you people doubting that the K&N can do it...just try it? It's an easy enough fix, it worked for me and its worked for other people. Throw the stock paper filter in and see if it changes it. It made sense to me that it would be a MAF problem because it was so intermittent and unpredictable. If it had been a boost leak it would've been a little more consistent, and boost leaks don't just go away after a few minutes of driving; they're pretty static.

For the record, I had the issue when I wasn't running my AC. Also, it happened consistently one day, I cleaned the MAF, and it went away. After that, I changed out the K&N drop in for the stock paper filter, and it has been perfectly fine with AC on or off. Just try it if you doubt it. It may not be your fix but it could be. Either way I believe I'll be selling the car...fit and finish is really starting to show its true condition. Rattles and various problems....

 

the only dryflows you have out there is AEM and Injen and no one else. its just pulling regular maintenance to keep the MAF sensor clean from messing up later whether you have a dryflow or oiled.

 

well this forum is alive again. after discovering my ZZP Catless and Injen CP not being the cause to the problem. 1badblueberry from Raleigh saw all the airloads reading correctly without a hick up on HPTuners log. I'm blaming the dealer for miswiring and going to have a talk of how the work was done. I bet the mechanic crimpped my my damn wires, instead of soldering them like Terminator without issues, then I will curse the dealer with a 1000 deaths of stupidity. these are the two error codes P2261 and p0236.

 

I'm soldering my connections tomorrow..... I know mine were crimped because I have looked at them already.

 

yeah the car did kicked into limp mode yesterday w/o a CEL. So, its gotta be a sensor issue with the wiring. I'm at 7200 miles with the GMS1 and drove round trip from Raleigh without going into LIMP mode. My fuel trims were fine, and 1badblueberry was surpised with the Injen CP and Catless DP not throwing it off. I'm fixing to say the hell with the GMS1 and get a tune.

 

Tuned or not it will still throw it off

 

what do you think what it is?

found this site with the P2261 https://www.cobaltss.net/forums/problems-service-maintenance-69/pi-lnf-intermittent-dtc-p2261-184458/
here is another from hptuners http://www.hptuners.com/forum/showthread.php?t=27881

 

The sensors. They will continue to do there job regardless of what tune you run. It can go into limp mode on any tune. Zip tie your lower sensor to the wires located on the left of them so that your wiring is running vertical (up and down) | . It might still do the slight boosting between shifts but it wont go into limp mode anymore.

Take it to the dealer.

 

1badblueberrySC mention about the bypassvalve might either have a crack or a vacuum line leak to the solenoids are located. the charts read the Injen CP and ZZP Catless just fine without any immature process taking place. I'll check my vacuum lines. I don't know how I can check that.

I'll take a look, someone has shown a picture about it and never had issues since. I already did the soapy formula to check for leaks on my Injen CP and looked under the car for cracks in the intercooler and coldside and nothing.

 

Disconnect the hose from the BPV and blow on the end of it. You will hear air coming out of the solenoid. I don't know what the case would be with that.

 

so I disconnect the vacuum line is from the triangle shape is and blow it with my mouth?

 

Disconnect it where it's connected to the BPV above the intake.

 

gotcha and then what?

 

I honestly don't think this has anything to do with anything though. It's just the sensor wires need to be soldered or h.e u spell

 

or just go to the dealer and tell them to honor the warranty on the GMS1 and checked the vucuum lines.
